THE NUMBERS, EXPLAINED
How to use this calculator.
Reference segments are nonoverlapping; covered seconds are already unioned within each segment. Presence is measured, not transcript accuracy or equivalent meaning.
Start with your inputs
Enter reference audio segment durations (seconds), verified transcript-covered duration per segment (seconds). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Reference audio segment durations (seconds) | 10,20,30 |
| Verified transcript-covered duration per segment (seconds) | 10,15,0 |
A worked example
With the example inputs above, uncovered duration by segment (seconds) is 0, 5, 30. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Uncovered duration by segment (seconds) | 0, 5, 30 |
| Duration coverage (%) | 41.666667 |
| Incomplete segment row numbers | 2, 3 |
How this is calculated
Uncovered duration by segment (seconds)
Subtract verified transcript coverage from reference duration.
Duration coverage (%)
Divide covered seconds by all reference seconds.
Incomplete segment row numbers
Identify segments with uncovered duration.
Symbols and units
- a
- Reference audio segment durations (seconds)
- b
- Verified transcript-covered duration per segment (seconds)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Reference segments are nonoverlapping; covered seconds are already unioned within each segment. Presence is measured, not transcript accuracy or equivalent meaning.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Uncovered duration by segment (seconds); Duration coverage (%); Incomplete segment row numbers. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Reference segments are nonoverlapping; covered seconds are already unioned within each segment. Presence is measured, not transcript accuracy or equivalent meaning.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
